H.' WILLIAM DOPP, OF BUFFALO, NEW YORK, ASSIGNOR TO HIMSELF AND JAMES E. THOMSON, OF SAME PLACE.

Letters Patent-No. 105,052, dated July 5, 1870.

The Schedule referred to in these Letters Patent* and making part: c! the same.

I, H. WILLIAM Dori', of Buffalo, in the county of Erie and State of New York, have invented a new Device for Canceling Adhesive and other Stamps; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had tothe accompanying drawing and the letters of reference marked thereon.

The nature of my invention consists incuttin'g or punching the characters of the date, day, mont-h, and year, clear-out and through the paper stamp, andgdoeument to which lthe stamp may be attached, hythe application of male dies or punches of the shape of the characters, as desired, the 'same to operate in' combination with a strip ot' soft metal, pasteboard, or

other suitable' material, so that the stamp to' be caneelcd is to be placed between the male punches and the soft metal, pasteboard, or other suitable material, and the said punches to punch through the paper stamp, and document into the soft metal or pasteboard, in older to 'dispense with corresponding female dies.

I refer to the drawing which makes part of the following specification, and in which a canceling-machine is represented in a longitudinal section.

Letter A is the Inain body or frame of the machine.

B is the diewhee1lcver. It is secured to frame A at B1 by means of two pivotsset-screws, land is provided with' two wire springs, C, one on cach side.

These springs have for their object bringing or raising the lever up again after it has been depressed by the action of the lever and eccentric D.

B is also provided with a cutter, E, which makes, in conjunction with cutter El, a pair ofshears, for the purpose of cutting up the strip of soft met-al or pasteboard that has already served for the punching or cutting ol' characters at B2.

Bz is a set of wheels, having on their faces raised figures, of such shape as to answer for cutting through several sheets of paper whenever B is depressed by means of D. A

F is a tape of soft metal or pastehoard, of about forty feet in length, which is wound up to a I'oll of about four inches in diameter, which roll is secured upon a mandrel, F2, and to the rear 'part of frame A.. Said tape runs from Fl overv two guide-rollers, F3 F,

- up tothe bed A, and along underneath the embossing-plate G. Of said embossing-plate a portion is cut out in the center, so as to expose the tape F to the figures or punches of wheels B2. The bed at A is somewhat raised, so that thetape F will be about even with the top ot' the embossing- .ratchet-wheel and pawl and connecting-rod, by means o'f which motion is transferred from lever B, as plainly illustrated by dotted lilies in the drawing.

The roller H is smooth on its periphery and not in direct connection with H; it acts more as a support and anti-friction roller than as feed-roller. l

Fis pulled along successively Athe length of one tignre or of wheels B", so that the figures or punches of 1?2 will always meet a blank spot on the tape not yet defaccd by the action ofthe punches, whenever the the same are depressed to -produce a new cancellation.

It will be observed that as the feed-I'ollers H and H pnll the tape along, it will run into the shears E, and be 4cut up successively as the tape feeds along, in order to get rid' of the portion of the tape F already used; the chips to drop down iut-o a receiving-box, I, from where they may be removed whenever it becomes necessary.

Claim.

Having t-hns fully described my invention,

What I desire to secure to me by Letters Patent For the purpose of producing acanc,elingstamp, that will cnt or punch characters out and through a paper stamp, check, or other documents, without the application of corresponding female dies and punches,

the soft metal, pasteboard, or other suitable strip of material, in combination with male dies or punches,`

automatically fed-ibrward, substantially as described, and as and for the purposes set forth.

H. WILLIAM DOPP.
